8 Claims.

(Cl. 'l2-38) This invention relates to an interlocked double wall and more particularly to a novel type of interlockable brick unit for use in the construction of building walls.

\ Heretofore, brick building Walls have been laid one above the other with mortar or cement between them. They have been reinforced by means of wood and/ or iron beams. Furthermore, such Walls, While being able to withstand considerable stress and strain, are relatively expensive since they require crossbeam supports and relatively highly skilled workmen.

With the above disadvantages in view, it is an object of my invention to provide, as a fundamental building unit, a brick of such simplicity that relatively little skill in brick laying is required.

It is another object of my invention to provide a brick of such outline that it can be readily interlocked with other bricks of similar construc- Fig. 5 is a top plan view showing the combination of the units illustrated in Figs. 1 to 4, inclusive;

Fig. 6 is a side view of Fig. 5; and

Figure 7 is a top plan View similar to Figure 5 showing the combination of the brick units Iprovided with a suitable filler material.

Referring now more particularly to the drawings in which similar reference numerals refer to like parts throughout, it will be noted that I provide a building brick I 0 containing along body tion so that it will form a completed wall for l lation therein of piping or conduits can be laid and which spaces may be lled with any suitable ller or material such as concrete or insulation material.

A more specic object of my invention is to provide a brick unit having vertically extending means with intermediate spaces between the means for interlocking with similar units, said means being provided with male projections and notches adapted to engage the notches and projections, respectively, of adjacent brick units.

Another specific object of my invention is to provide a combination of interlockable brick units forming intermediate spaces for the installation therein of piping for any suitable purpose.

Other objects and advantageous features of my invention will become apparent from the following detailed description taken in connection with the attached drawings wherein:

Fig. 1 is a preferred embodiment of my invention showing a perspective view of a brick unit;

Fig. 2 is a lperspective view of another form of the unit shown in Fig. 1;

Fig. 3 is a perspective view of a modification of the embodiments shown in Figs. 1 and 2 and is used in connection with said embodiments to join with the ends thereof at right angles;

Fig. 4 is a perspective view of a brick unit used for joining the opposed ends of the embodiments shown in Figs. 1 and y2; i i

portion I I. Said long portion contains a number of intermediate, vertical, upper and lower extensions I2 and I3, respectively, whose side walls I4 and I5, respectively, are provided with a notch or semi-cylindrical recess I6 which is adapted to retain therein cement, mortar, or other binding material when said brick IU is laid. It will be noted that said notches IE are disposed in the center of the Walls I4 and I5. There are also provided at the end of said brick I0 terminal seotions Il whose respective inner, upper and lower faces I8 and I9 are provided with a notch 20 While the front and rear walls 2l and 22, respectively, of said terminal sections are also provided with vertical notches or recesses 23 and 24, respectively. `Intermediate the extensions or sections I2 and I3, as shown, it will be noted that there is provided an upper and lower intermediate space 25 and 26, respectively, for accommodating an adjacent brck unit of similar construction in the corresponding intermediate spaces 25 and 26 thereof, as shown in Figures 5 to 7 of the drawing.

The unit Ill as shown in Fig. l is intended for the corner portion of one or more vertical walls, while the unit Illa shown in Fig. 2 is of the same construction but is much shorter than that shown in Fig. 1 and is intended for the front portion of the wall to be built with such units, although either unit, because of the similarity of construction, may be used interchangeably and at right angles relatively of each other.

In Fig. 3, I show a joining brick unit 2l Which is substantially of H-shape and consists of tWo vertical sections 28 and 29, respectively, and an intermediate, interconnecting, horizontal section 3U. The upwardly extending sections 28 and 29, respectively, are each provided at their opposed faces 3| and 32, respectively, with a vertical notch, recess or groove 33, while the front, side and reati` faces 34, 35 and 36 respectively, of the sections 28 and 29 respectively, are provided with vertical or male projections 31 which are adapted to engage the notches or recesses 23 of the terminal portions I1 of the units shown in Figs. 1 and 2, respectively.

In Fig. 4, I show a brick unit 38 in which the outer face 39 is straight while the two side faces 40 and 4I, respectivelyl are each provided with a projection 31 so as to join with the notches 23 of the terminal portion I1 of the unit I0 and Illa shown in Figs. 1 and 2, respectively. The inner face 42 of said unit as shown in Figs. 4, 5 and 7 has a recess 43 so as to accommodate a suitable lling material 44 when a plurality of walls are constructed such as shown in Figs. to 7, inclus1ve.

It will be noted that blocks I0 or I0a, respectively, as shown in either Figure 1 or 2, can be superimposed above each other crosswise, whereby the intermediate spaces 25 and 26 of one block are adapted to accommodate the portions between extensions I2 and I3 of a similar type of block so as to be bounded between the terminal and extending portions of each block.

It will also be noted from the foregoing description taken in conjunction with the accompanying drawings that a block of the type made according to my invention can be readily superimposed above blocks of similar construction whereby one or more walls can be built within a relatively short time, it being understood that the blocks when superimposed are at right angles to each other. The spaces 25 and 26 between any protruding terminal portions as shown in Figs. 1 and 2, are lled in by means of interconnecting block 21 or covered by blocks 38 as shown in Figs. 5, 6 and '1. The terminal portions I1 can be readily joined at right angles with interconnecting block 21 or 38 whereby the projections 31 of either block will t into any of the notches 23 or 24 of said terminal portions. Furthermore, for example, block 21 may be tted between portion l1 and upward or downward extension I2 or I3 to obtain a desired t. In such case the portion 30 of block 21 ts in the intermediate space 25 or 26. In the alternative the portions 28 or 29 may t between such portions above indicated. By a combination of such blocks units it is relatively easy to lay piping or conduits in a vertical or horizontal manner in these walls as shown in Figs. 5 to '7. Furthermore, the intermediate spaces formed between the walls built by these blocks can be readily lled in with any suitable material 44 depending upon the purpose for which such material is used such as cement. mortar, or sand as a filler, or insulating material for insulation purposes.

Blocks made according to my invention are highly useful for any type of construction work such vas for foundations, for building inside and outside walls, for window or door frames. .These blocks are made of the usual type of construction material and are easily interlockable, are provided with notches intermediate the terminal portions of the block for retaining binding material therein while the terminal portion of the building blocks are provided with front, side and rear walled recesses or notches which are adapted to accommodate the projections of the interconnecting blocks such as shown in Figs. 3 and 4.

Having described illustrative embodiments of the invention, it is pointed out that various changes and modifications therein may be made without departing from the scope of the invention as set forth in the following claims.
